MACHINE FOR MAKING SHEET-GLUE.

T0 all 'whom it may'concem: Be it known that I, ROY MORGAN, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have inventednew and useful Improvements in Machines for Making Sheet-Glue, of which-the following is a specification. v

This invention has for. its general object to provide a machine for making sheet glue which shall be simple in construction, efiective and reliable in operation and economical f manufacture.

Among the detailed objects of the invention are a novel construction and operation of the glue-spreading construction and operation of a glue gathering device.

Other objects ofthe invention relate to details of construction, and .to combinations and operations of parts, as will hereinafter.

more clearly appear.

An embodiment of the invention in the form best known to me is shown in the. accompanying drawing, in which:-.

Figure 1 is a View mainly in side eleva tion and partly in broken section, of a machine constructed according-to myf'invention; J

opposite sides thereof, are mounted plates 18, each of which. is provided with a deep groove 19 and a shallow groove 20, said grooves being adapted 'to receive the end trunnionsj 21 of a gathering roller 22 Mounted on the rear uprights 11 is a hinged scraper 23, which is preferably curved concentrically wlth the roller'22. The carriage 10 with the parts just described mounted ta' 1e 1 and communicating centrally of its n the rear end of thecarriage, and on thereon is moved back andforth over the table 1 by means of sprocket chains 24, -lo- 1 cated on either side of the table and to which the carriage is connected by means of extensions 25 having their ends secured to said chains.

operated in the followingmanner:-

Mounted in bearings 26 at'either end-of the table are shafts 27 provided at. their ends with sprocket-wheels 28 for receiving and actuating the chains 24. The shaft 27 The chains 24 are mounted and at the forward end of the machine is pro a videdwith a pulley 29 which is driven by a belt 30 from a motor 31. One of the chains I 24 is provided at the proper interval with two stops, 2, 33, respectively. Mounted on the same sideof the machine as this chain is a two-Way switch 34, having contact 35 and 37, respectively, and having contact end 36, and a'free end of'which', is

in the line ofmovements of the stops 32 and 33; e

Theoperation of the machine, far

shown inv Fig. 1, engagement with the, contact .37. This riage v 10 is drawn being 1n the a position 7 a the operator i turns the switch 38 to cause its upper end 36' to make ice 1 rails 8 until 1t reaches the forward end of the switch arm 38 and turn the latter out of the table, whe p the stQp 33'wi11 eng ge places the motorjin o'peration,'.and the; car by the chains 24 ovpr the engagement with the contact 37 to the neutral position shown in Fig. 1, thereby stopping the operation of the motor. During this movement of the carriage the roller 22 will be supported by its trunnions in the shallow grooves 20, the scraper 23 having previously been turned to the position shown in dotted lines in Fig. land being held in such position by the roller.

The operator now manually turns the switch arm 38 to make engagement of its end 36 with the contact point 35, whereby the motor will again be placed in operation, but so as to turn in the opposite direction to that first described and thereby move the carriage toward the rear of the machine until the switch arm 38' is engaged by the stop 32 and again brought to neutral position. After the carriage'has moved a short distance toward the rear end of the table the handle 15 is then operated to open the valve 14, and a desired number of the faucets 17 being already open, the lue flows out on the glass top 6 and forms a airly uniform sheet.

When the carriage is brought to a stop at the rear 'end of the table the valve 14 is closed and the switch arm is then operated as first above noted to cause the carriage 10 to be moved back to the front end of the table. During this time the sheet of glue is cooled.

After the carriage reaches the front end of the table the scraper 23 is lowered so as to restupon the glass top 6 and the roller 22 is placed with its trunnions in the deep grooves 19. The carriage is now started toward the rear of the table and the scraper 23 lifts the sheet of glue and turns it. over on the roller 22 as the latter is rotated by frictional contact with said sheet. The sheet is thus caused to be wound upon said roller, as indicated more clearly in Fig. 3. During this time the faucets 17 are opened so that anew sheet of glue is being laid as the one is being taken off the table. It being understood that by the time the carriage is brought again to the front end of the machine the layer of glue has sufiiciently cooled to form a semi-plastic sheet which is removed in the manner just above described.

At the rear of the machine there is a supplemental structure comprising, essentially,

'two side rails 39 and uprights 40, the latter pro ecting above the rails 39 to form stops 41. On the end of the rear shaft 27 there is secured a gear 42 which is in mesh with a gear 43 secured on the end of the shaft 44 which is mounted in bearings 45 extending beyond the rear end ofthe machine. On the shaft 44 is a roller 46, over which, and a corresponding, suitably-supported idle roller (not shown) is assed an endless belt 47.

The carriage aving been moved to the position shown in Fig. 1, with a sheet of glue wound upon the roller 22 as described, the said roller is now lifted out of the grooves 19 and its trunnions placed on the rail 39 and rolled along said rails until brought to a stop by engagement with the stops 41. A tray 48 is placed upon the endless carrier 47, another roller 22 is placed with its trunnions in the shallow grooves 20, and the switch arm 38 is turned to start the motor in operation and again return the carriage toward the front end of the machine for a new sheet removing and spreading op eration. In this movement of the sprocket chains the engagement of the gear 42 with the gear 43 will cause the endless conveyer 47 to move outward, as to its upper portion. In this movement the end of the sheet of glue, indicated by the numeral 49, is placed on the forward end of the tray 48 and as the tray 48 is moved outward by the conveyer the sheet of glue is laid upon said tray. When the desired length is wound oil, that is to say, a length of glue corresponding to vided with a spreader for depositing glue upon the table in the rearward movement of the tank, a roller movable with said tank in its rearward movement in frictional engagement with the layer of glue deposited on the table, and a' scraper also movable with said tank and operating in the rearward movement thereof to lift the sheet of glue and turn it into contact with said roller.
